ApplicationM'ay, 1.6, 1941,.S erial No. 3.9.3.703 r9; Glaims. (01. 146-102) This invention relates to slicing machines. in general, and particularly to: slicing. machines. of the so-called push-pull type having a carriage. adapted to be moved manually in a. rectilinear direction past the cuttingedge of. a. continuously rotating circular knife. A I

An important object. of the present invention is the provision of novel means-for a push-pull slicing machine, whereby the carriage may. be. mechanically connected to the means. which drives the knife sothat the machinefmay be operatedeither manually. or mechanically.

Another important object of. the. inventionisto. provide a slicing. machine;- with. operable means whereby a knife and a reciprocable carriage may be driven mechanically, or the knife. driven mechanically and the carriage reciprocated.

manually.

A further imnortantobject of the inventionis.

to provide, a slicing machine of. the so-called. push-pull type with new-a.nd.novel mechanism. whereby the operation. of an operable. member will convert. the machine into'a full. automatic machine, permitting automatic. operation: of the carriage and knife. or manual operation of. the carriage and continuous. mechanical'operatmn of. the knife, as selected; v .j

Still'another object ofthe. invention residegin theprovision of. new and; imp roved...means for selective automatic ormanual operationwhereby. the carriage may be either. automatically or manually operated; in a. rectilinear-path across the cutting, plane. of I acontinuously operating. cir-. cular knife.

A still further object of. the invention. isthe provision. of new. and. simple, means. .for. rendering the slicing machine capableoi. selective mechanical or manual operation.

stance carriage 4. The carriage 4; is provided with. a sleeve 5 which. surrounds. the. guide. rod or bar 2 and slides freely thereon. The guide. bar 3. is, operatively engageable with guide, means on the carriage. andv permits the carriage to. be slid freely back and forth. in. a.- rectilinear path above they base Iv and; past the. cutting. plane. of. a

circular slicing ,or cutting ,knife 6.

'A gauge plate 'I is mountedv on the knife.- side of the machine and. is operated. by ahand index member 8' to move the gauge. plate toward" or away from the slicing plane so to. cause. slices of different thickness to be out by the knife. Substance on the substance platform of the carriage is pressed against the. gauge plate I. by a pusher plate 9', and as the carriage is pushed forwardly (away from the operator) a slice will be cutfrom the substance. The thickness ofthe slice will be equal. to the distance the gauge plate is away from.

the" cutting planeof the knife, 6. The carriage,

4' is provided witha handle Illwhich is adapted to begrasped by the operator and pushed or pulled to move the carriage in a rectilinear path. Theslicing machine so far described is the well.- known push-pull slicing machine as manufactured bythe U. S. Slicing; Machine. Company of La Porte, Indiana;

The present invention has to do withoperating the carriage electrically, there being means provided; to connect the. carriageto a constantly driven member whereby the. carriage may. be operated selectively for either automatic or manual operation as desired;

A- shaf-t H, from the motor (not shown) for driving the circular knife 6', carries a gear l2, Fig. 2 which meshes with a gear. [3; on a longitudinal'shaft orrod l4=.' The shaft or rod, Mis mounted in suitable bearings I 5v and Ni carried by the base and is constantly driven by the. motorshaft H. The rod M is provided with a double groove ll' so-as toefiect'movementof the carriage in each. direction when an. operable member I8, supported by the. carriage is in mechanical' contact, or in operable engagement, in

the space or. grooves l'l'between the lands or ribs of the member M. The operable member IB' is .in-

the. form of a fitting 19; Fig. 2, rigidly secured to a bracket member 20 which is. fastened to the sleeve 5 on the carriage. The bracket. member 28 comprises. a base. portion 2! which is provided cular openings through which the guide rod 2 passes. Springs 24 are positioned between the end of the members 23 and the ends of the sleeve 5 so as to permit a certain amount of yield or resiliency when the carriage reaches the end of its forward and rearward travel. A certain amount of free longitudinal movement is provided by theslot andpin connection "between the bracket with the sleeve 5. The bracket 20, therefore, is secured to the sleeve 5, but provides for a certain amount of flexibility because of the springs 24. This bracket 20 secures the fitting.

ating point 21 with a groove |1 when the handle full lines in Fig. 2, at which time the head 28 I9 rigidly in position and is adapted to move with the carriage. Conversely, however, the drive sponding movement of the carriage 4.

The fitting I9 is hollow, as clearly shown in plunger 25 which is urged Fig. 2, and receives a toward the member M by means of a spring 261 The end of the plunger 25 is provided with an operatingend or point 21 which is adapted to be moved into engagement with a .groove'll1. The

provided with an operating the base surrounding theslot 33 so as-tohold the member-3l in a predetermined or pre-select-.

ed position. Aspring member 36 is connected .to the bar- 32.and .to .a part of the frame. to urge tion toward theoperator .(to the left, Fig- 2).- When thelatch 35 is outof engagement'with a partof the base-or-frame,- the spring .36 will urge the bar 3| to the left, Fig. 2, and move the bar sothat the spring 26 will .be. permitted to raisethe driving end 21 of the plunger. 25..into engagement'with a groove |1.-- Theend of-the member, opposite to the handle 34,isslidingly received 'on a.pin 31 which isfixed to theend of the frame (to the right, Fig. 2). The forward end of the member or pin-31 iscut away, as shown at38, sothat when the handle 34 is pressed .downwardly, and the spring '36 urges the member 3| end of the member 3| passing over the inclined partior cam! on the member 31 and being supported on the cut away portion 38 thereof. The member 3| is therefore caused to rise to the position shown. in dotted lines in Fig. 2, whereby the operating end orpoint 21 of the plunger will be-in engagement with .a groove l1 underaction of the spring 25. When the handle member 34 is moved inwardly, as shown in full lines inv Fig. 2, the end of the member 3| rides downwardly upon the cam 40 into engagement with. the .circula'r part 39 of the member or pin 31 and the member 3| is therefore caused to lower so. as to move the operatingend or point 21 out of a groove |1.'. The member32-also has an upwardly inclined cam surface which operates in the slot 33. This cam surface incooperation with the cam surface 40 on the member 31 causes. the channel shaped member 3| to be raisedor lowered to permit engagement or disengagement of theopermg movement of the fitting lllziwill cause corre The end of theopand there is a latch 35 .on apart of the bar which-is adapted to engagethe material of.

Therefore, there-will be '"no positive connection between the'memberv l4 and the carriage, and the carriagewillbeifree to. be operated back and forth manually .ina rectilinear path. However, should it be desired to make the device fully automaticallyorj: mechanically operated, the knob 34 is moveddownwardly in the slot 33 so as to disengageithe latch 35 from the base at which timethespring 36 will pull the channel-shaped memberl3l to the left'of 21 will be-in operating engagementv ith the:

V certain direction 7 until the carriage reaches. the end:' ofiits travel, at which timethe. point 2.1 is causedto me into engagement with the other groove; This latter engagement causes thecarriage to be moved in an opposite direction.v The double groove l1. causes the carriage to be moved forwardly awayfrom the operator to perform t he slicingstrokaand when the carriage reaches the end of; its operativetravel in that direction, the fitting [5 will beat the far end of the machine at'which time the finger 21 will engage the'other of said grooves causing the carriage. to .return to position at the operators end of the machine. Assoon' as the.carriage reaches the end of its returnmovement. the operating point or end 21 will become engaged again with the first groove andicausethe' carriageto perform another slicing stroke; This operation continues and causes continuous back and forth rectilinearmovement of the carriage. Thereforawhen' it is desiredtohave "a full automaticallyor'mechanically operated machine, the knob 34is operated so'as to retract it'from its atch; ".but"when it is desired to have a conventional push epullmachine, the operating knob is pushed inwardly, as shown in full linesin Fig. 2, causing 'disconnectioniof the plunger'frorn'the grooves in the-member 14.
